Hello!

morning

random core function of the day

clojure.core/bases
([c])
  Returns the immediate superclass and direct interfaces of c, if any

morning

How often to you use bases?

How many people knew about bases?

nope , nor have I ever felt the need for it

ok, dumb question time - is there a core function that maps a function and a unique sequence (or a set) into a map where the keys are the original sequence, the values are f(key) ? like group-by but the other way around?

so thing(inc, #{1 2 3}) would produce {1 2, 2 3, 3 4}

I can do it with (zipmap vals (map inc vals)) but it feels like there should be a single function, my cheat-sheet-fu is failing me.

I don't think there's one, zipmap is it :)

I’ve also been known to abuse (into {} (for [x things] [x (f x)]))

or in this case (into {} (map #(vector % (f %)) things) - but somehow I find the for syntax easier

or (into {} (map (juxt identity inc) #{1 2 3}))

for juxt fun

why is there no emoji?

austerity

bwahahaha 🙂

haha nice

@korny there is also partition with overlap

(partition 2 1 (range 10))

@malcolmsparks That's really nifty 🙂
